Currently, commercially biodiesel is produced from the refined edible vegetable oils such as Schlichera oleosa seeds oil by alkaline catalyzed esterification process. This process is reported to be not suitable for unrefined non-edible vegetable oils because of their high free acid value. Thus a two-step esterification method was developed to produce methyl ester (bio-diesel) from high FFA Schlichera oleosa oil.
